[Mailman-Users] use of Python strings in template files

Thank you for your timely reply. I sort of understand what you are 
saying. I edited MailList.py to look like this:

            {'email'      : newaddr,
             'listaddr'   : self.GetListEmail(),
             'listname'   : realname,
             'cookie'     : cookie,
             'requestaddr': self.GetRequestEmail(),
             'remote'     : '',
             'listadmin'  : self.GetOwnerEmail(),
             'listinfo_url : listinfo_url,
             'confirmurl' : confirmurl,
             }, lang=lang, mlist=self)

I then restarted Mailman.

When I tried to subscribe to a list that required confirmation, I got this:

Bug in Mailman version 2.1.5
We're sorry, we hit a bug!
If you would like to help us identify the problem, please email a copy of
this page to the webmaster for this site with a description of what
happened. Thanks! 
Traceback (most recent call last):
  File "/lists/scripts/driver", line 87, in run_main
  File "/lists/Mailman/Cgi/subscribe.py", line 96, in main
    process_form(mlist, doc, cgidata, language)
  File "/lists/Mailman/Cgi/subscribe.py", line 176, in process_form
    mlist.AddMember(userdesc, remote)
  File "/lists/Mailman/MailList.py", line 868, in AddMember
    {'email'       : email,
NameError: global name 'listinfo_url' is not defined

So, I removed the listinfo_url entry and it is back to normal.

Any idea what happened?
